Why does fluid stick to the outflow object?
In the example you showed, the velocity was probably set to something like 2.0 along the Z on the Inflow Sphere which means the water hits the top of the domain and runs down the sides.





Also with your Domain object, I would try experimenting with some settings.

These are the settings I set to create this scene effect. I don't know if this was more what you were looking for with yours.



I baked this with very low resolution. I'm sure with higher resolution, it would look much better but hopefully you can see the effect.
